The placenta is the container that keeps the baby isolated from the mother. The fetal blood flows through the baby, out the umbilical cord to the placenta and no further. The placental membrane separates maternal blood from fetal blood.Oxygen and nutrients in the maternal blood in the intervillous spaces diffuse through the walls of the villi and enter the fetal capillaries.he fetal blood flows through the baby, out the umbilical cord to the placenta and no further.

Fetal Blood Flow. A fetus (baby) is fed, or nourished, by the mother through the placenta, which is attached to the umbilical cord. In the placenta, the mother's blood and the fetal blood both flow through vessels that are very close together.But the mother's blood does not mix with the fetal blood.When the mother's blood is close to the fetal blood, oxygen and nutrients move from the mother's blood into the fetal blood.As the blood flows through the fetus, it picks up waste products and returns to the mother through the umbilical cord.etal Blood Flow.
